Document Summary
1. 5 mile run good example of field test due to. Field tests not considered replacement tests for the direct measurement of vo2 in research studies. Tests that prescribe walking may be most appropriate for middle-age & older adults. Acsm does not feel a need to recommend a medical examination for apparently healthy older adults prior to performing test of moderate exercise. P(cid:396)ovides a (cid:395)ua(cid:374)titative (cid:373)easu(cid:396)e of a pe(cid:396)so(cid:374)"s capacity fo(cid:396) aerobic atp resynthesis. Important indicator of how well a person can maintain intense activity for longer than 4-5 min. A high vo2max requires the integrated and high-level response of diverse physiologic support systems. Oxidative metabolism predominates for events lasting > 2 min. Highly trained runners performing the 1500 m in 3 min 55 s received 84% of their energy from aerobic pathways. There is not enough atp produced to sustain muscular action beyond a couple minutes.
